Answer & Explanation

 

  1. 5

 

  1. 2

 

  1. 4

 

  1. 3

 

  1. 4

 

  1. 1

Since the ratio of no. of days taken by Dinesh and Ganesh

= 3 : 4

ED : EG = 4 : 3,

Since the total efficiency of Dinesh and Ganesh is (4 + 3 = 7) and with this efficiency they complete remaining work after 4 days ( 100%–44%=56 %) in 8 days. It means they did 8% work per day.

7 efficiency = 8 days 56% work

7 efficiency = 1 day 8% work

In first 4 days total work by Dinesh and Ganesh is 32%.

Therefore Ramesh must have done 44% – 32% = 12% in 4 days.

So in 1 day he does 3% work.

So total work he will do in 33 1/3 days

 

Further, 7E —–> 8% of total work

1 E —–> 8/7 % of total work

 

3 E (Ganesh) —–> 24/7% of total work

 

Time taken by Ganesh to finish the work alone = 100*7/24 = 87.5/3 days

and 4E (Dinesh) —–> 8/7 4% of total work = 32/7% of total work

Time taken by Dinesh to finish the whole work alone

= 87.5/4 days

 

Ramesh —–> 100/3 days(Slowest)

 

Dinesh —–> 87.5/4= 21.875 days (Fastest)

 

Ganesh —–> 87.5/3 (Second fastest).

 

Therefore option 1 is

correct.

 

  1. 2;

DR : DG = 100/3 : 87.5/3

ER : EG = 87.5 : 100

 

Required ratio = ER : EG = 7 : 8

Thus less efficiency = 1/8 * 100 = 12.5%

 

  1. 5; The ratio of water and milk in the tank according to the proceeding is (20% + 40%) : (8% + 32%).(In first 2 hours water will be restored in tank by 20% and in next 4 hrs.40% more, and milk as per calculation 100%, in 12.5 hrs.

 

So in 1hr only 8% of whole tank will be filled up. Therefore in 4 hrs 32% of whole tank is filled up.)

 

So present ratio of water to milk = 3 : 2

 

And the second ratio of water to milk = 2 : 3

 

  1. 1;

1 × 2 × 3 × 4 = 24 numbers, it mean at every place digits

will occur six times.

 

Sum of one column = 6 ( 1 + 2 + 3 + 4) = 60

 

Hence, sum of all the numbers

= 60 × (100 + 101 + 102 + 103)

= 60 × 1111 = 66660

 

  1. 4

Ratio of sides of the triangle = 1/2 : 1/3 : 1/4 = 6: 4: 3

 

Let the sides be 6k, 4k and 3k respectively.

13 K = 52

K = 4

Sides are 24 cm, 16cm and 12cm.
